Genes affected
HOXA13 (HGNC:5102): (homeobox A13) In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. Expansion of a polyalanine tract in the encoded protein can cause hand-foot-uterus syndrome, also known as hand-foot-genital syndrome. [provided by RefSeq, Jul 2008]
HOTTIP (HGNC:37461): (HOXA distal transcript antisense RNA) This gene produces a long RNA in antisense to the HOXA gene cluster. This transcript may regulate expression of HOXA genes in cis. This gene is upregulated in tumors and is implicated in the promotion of cell proliferation. [provided by RefSeq, Dec 2017]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4
?
    BP4 - Multiple lines of computational evidence suggest no impact on gene or gene product (conservation, evolutionary, splicing impact, etc.)
Computational evidence support a benign effect (BayesDel_noAF=-0.46).
BP6
?
    BP6 - Reputable source recently reports variant as benign, but the evidence is not available to the laboratory to perform an independent evaluation
Variant 7-27199181-G-A is Benign according to our data. Variant chr7-27199181-G-A is described in ClinVar as [Benign]. Clinvar id is 1643421.Status of the report is criteria_provided_single_submitter, 1 stars.
BP7
?
    BP7 - A synonymous (silent) variant for which splicing prediction algorithms predict no impact to the splice consensus sequence nor the creation of a new splice site AND the nucleotide is not highly conserved
Synonymous conserved (PhyloP=0.407 with no splicing effect.
BS2
?
    BS2 - Observed in a healthy adult individual for a recessive (homozygous), dominant (heterozygous), or X-linked (hemizygous) disorder, with full penetrance expected at an early age
High AC in GnomAd at 16 AD gene.
