Is there a feature film that's about some genetic disorder or concerns
genetics in any manner? What's it's name?

Hi addie09,

Here are some movies that involve some form of genetic disorder:

Jack (1996)
"Ten-year-old Jack Powell (Williams) suffers from a rare genetic
disorder that causes him to age at four times the normal rate so he
looks like a 40-year-old. His family, fearing ridicule, has kept him
isolated but since Jack's so lonely, they finally agree to let him
attend school. This new fourth grader isn't the only one with a lot to
learn."

Follow The Stars Home (2001)
"Kimberly Williams marries love-of-her-life Eric Close, only to have
him leave her when they learn that their first child will be born with
birth defects. However, with the help of brother-in-law Campbell Scott
(who is secretly in love with her) and her mother, Williams becomes
determined to raise the child on her own in this moving "Hallmark Hall
of Fame" drama."

Dancer In The Dark (2000)
"Selma, a Czech immigrant goes in search of a new life in America for
her and her ten year old son. She is given a starring role in the
local production of 'The Sound Of Music' and life seems relatively
good apart from the fact that she has a genetic disorder that will
leave her blind unless she can raise the money for an operation..."

Unbreakable (2000)
"Willis reteams with "The Sixth Sense" writer/director Shyamalan for
another spooky saga. He's not only the sole survivor of a train crash
but he emerged without a scratch, which intrigues Jackson, who suffers
from brittle bone disease..."

Lorenzo's Oil (1992) 
"Based on the true story of Augusto and Michaela Odone's efforts to
find a cure for their five-year-old, Lorenzo, diagnosed with the rare
and incurable disease ALD (Adrenoleukodystrophy). Confronted by a
slow-moving and clinically cold medical community, the Odones embark
on their own quest for a cure. Sarandon delivers an outstanding and
emotionally charged performance as Lorenzo's determined mother. Nolte
is his equally devoted Italian father, complete with black hair and
hand gestures. They are a powerful presence in a film which could have
easily degenerated into a made-for-TV movie, but is instead a tribute
to what love and hope can accomplish."

the point, informative and very helpful

Craniofacial disorder:  "Mask"

another option - Gattaca

"Futuristic story of a genetically imperfect man and his seemingly
unobtainable goal to travel in space."  (IMDB.COM)

while it is not about a specific disorder, it involves genetic
imperfection and what the future may hold for peoplekind.

Not forgetting 'Mask' (1985) starring Cher and Sam Elliott.
